Brilliant!! I started with the freeware version & I thought that was pretty darned good. being on a pension I gravitate to freeware, but muddling around, getting good support, etc.... I joined as a premium user. Also, when Firefox was going through it's Massive upheaval & everything was "hitting the fan"; I was tempted to move to another browser, but BLUR was even a help getting through that ugly time! Again - great support! Now, I am no great I.T. whiz-kid; I'm getting too old for that, but compared to other Privacy & Protection add-ons, Blur is a must for those like me that may be a tad Tech-challenged; this is a must have. Despite the fact I just found that it doesn't "Blur" Australian Purchase Cards it's still great. I still have other Privacy & Protection add-ons, in action - despite hardly knowing what I'm doing cos MOST App/Add-on authors assume too much prior knowledge. I ran a high level test to check vulnerabilities; to find that all was screwed down tight. Thanks, very much to Blur! There may not "be many Reviews" of Blur, but that may be 'cos there ain't much to complain about! That's my humble Aussie non-whiz-kid opinion. ;)
